memory-delta

Script Path Resolution

IMPORTANT: The scripts/ folder is in the plugin directory, NOT the current project.

From "Base directory for this skill:" above, derive the scripts path:

• •Remove /skills/memory-delta from the end
• •Add /scripts/ to get the scripts directory

Example:

• •Base: ~/.claude/plugins/cache/memory-keeper-marketplace/memory-keeper/13.8.3/skills/memory-delta
• •Scripts: ~/.claude/plugins/cache/memory-keeper-marketplace/memory-keeper/13.8.3/scripts/

Use this full path when running node commands below.

Trigger Condition

Auto-invoked when EITHER:

1. •Hook stderr outputs: [MEMORY_KEEPER_DELTA] file=delta_temp.txt
2. •Context contains: [MEMORY_KEEPER_DELTA] trigger pattern

If you see [MEMORY_KEEPER_DELTA] anywhere in your context, execute this skill immediately.

Execution Steps

1. •

   Verify file exists first (DO NOT SKIP):

   bash

   cat .claude/memory/delta_temp.txt | head -5
   

   If file not found or empty, STOP HERE - do not proceed.

2. •

   Call Haiku agent for summarization: Use absolute path (get from pwd):

   code

   Task tool:
   - subagent_type: "memory-keeper:delta-summarizer"
   - model: "haiku"
   - prompt: "Read {PWD}/.claude/memory/delta_temp.txt and summarize (1 sentence per ~200 words)."
   

   Replace {PWD} with the actual current working directory (absolute path).

3. •

   Validate Haiku response:

   • •If response starts with "ERROR:" → STOP, do not proceed
   • •If response is empty or says "file not found" → STOP, do not proceed
   • •Only continue if you have actual summary content
4. •

   Append summary to memory.md with dual timestamps: Run this single command (replace {SUMMARY} with Haiku's response):

   bash

   TS_UTC=$(date -u +%Y-%m-%d_%H%M) && TS_LOCAL=$(date +%m-%d_%H%M) && printf '\n## %s (local %s)\n%s\n' "$TS_UTC" "$TS_LOCAL" "{SUMMARY}" >> .claude/memory/memory.md
   

   WARNING: Do NOT modify this command. Copy EXACTLY as written.

   • •The date format uses single % (e.g. %Y), NOT %%Y
   • •%% in date means "literal %" which outputs format strings instead of dates

   Example output: ## 2026-02-01_1727 (local 02-01_0927)

5. •

   Update timestamp marker (use full path from above):

   bash

   node "{SCRIPTS_PATH}/extract-delta.js" mark-updated
   

6. •

   Delete temp file (use full path from above):

   bash

   node "{SCRIPTS_PATH}/extract-delta.js" cleanup
   

Failure Handling

• •If file doesn't exist in step 1: STOP immediately
• •If Haiku returns ERROR or empty: STOP, don't update/cleanup
• •If Task tool fails: Don't update timestamp, don't delete temp file
• •Next trigger will retry with accumulated content (temp file overwritten)
